This is the result of a lighting retrofit installed in its 200,000-square-foot facility in Altoona IA by SmartWatt Energy Inc, an energy-efficiency firm specializing in the refrigerated and frozen warehouse industry.

Committed to providing convenient and reliable warehousing services, Iowa Cold Storage is now focusing on reducing energy use, lowering energy costs, and conserving environmental resources. SmartWatt Energy’s Chicago IL office staff performed a construction-grade energy audit of the facility, and then engineered an action plan to replace 328 metal halide lighting fixtures with energy-efficient LED lighting. SmartWatt Energy chose LED fixtures for the project because of their superior performance in cold storage facilities.

The new energy-efficient lighting installed by SmartWatt Energy will reduce lighting-related energy consumption by 71%. It has led to the equivalent reduction of 577,889 pounds of carbon dioxide from the environment. According to US Environmental Protection Agency (EPA) estimates, this project will have the same environmental effect as planting 85 acres of trees or removing 55 vehicles from the road each year.
